Why Bonded EPDM Washers?

The bonded EPDM washer combines a metal washer with a flexible EPDM rubber backing to create a watertight seal around the fastener head. EPDM (Ethylene Propylene Diene Monomer) offers superior UV and weather resistance, making these screws a go-to choice for roofing, siding, and other exterior metal installations.

Ideal Applications

• Metal Roofing and Siding
• Industrial Steel Building Assemblies
• Pole Barn, Shed, and Agricultural Constructions
• HVAC Installation and Maintenance
• Any Project Requiring Bulk, Leak-Resistant Fasteners

Bulk Benefits

• Lower Cost per Screw: Save money by purchasing higher quantities.
• Project Efficiency: Keep a consistent supply on hand to reduce downtime.
• Professional Quality: Proferred® brand ensures high manufacturing standards.

Installation Tips

• Use steady pressure so the #3 self-drilling tip can fully engage metal surfaces.
• Align screw perpendicular to the work surface to optimize the EPDM washer’s seal.
• Avoid overtightening to prevent washer damage and ensure lasting water resistance.
• For fast, secure installation, pair with a 3/8 inch Magnetic Nutsetter.
